In the experiment to trace the path of a ray light a triangular glass prism. 1. If the emergent ray makes an angle 35 with the second face of the prism , then what is the angle of emergence. 2. Can the angle of deviation be zero and why?

Question

Philoid · Accepted Answer

1. The angle of emergence

2. No, because at the second refracting surface of the prism , a ray of light moves from denser to a rarer medium, it bends away from the normal, I.e., bends towards the base of the prism.
